Undervoltage protection is crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard.
However, the need for protection circuits to maintain the voltage and current within safe limits is one of the primary limitations of the lithium-ion battery.
Figure 1 shows an ultralow power, precision undervoltage-lockout circuit. The circuit monitors the voltage of a Li-Ion battery and disconnects the load to protect the battery from deep discharge when the battery voltage drops below the lockout threshold.
It contains both primary and secondary protections to ensure safe use of the battery pack. The primary protection protects the battery pack against all unusual situations, including: cell overvoltage, cell undervoltage, overtemperature, overcurrent in charge and discharge, and short-circuit discharge.
Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high. Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe)

Lithium-ion batteries are also frequently discussed as a potential option for grid energy storage, although as of 2020, they were not yet cost-competitive at scale. Because lithium-ion batteries can have a variety of positive and negative electrode materials, the energy density and voltage vary accordingly.
To reduce these risks, many lithium-ion cells (and battery packs) contain fail-safe circuitry that disconnects the battery when its voltage is outside the safe range of 3–4.2 V per cell, or when overcharged or discharged.

Conclusion Building a lithium battery involves several key steps. First, gather the necessary materials, including lithium cells, a battery management system, connectors, and protective casing. Begin by designing the battery layout, ensuring proper spacing and alignment of cells.
The desired nominal voltage of the battery pack is 11.1V. The nominal voltage of each cell = 3.7 V No of cells required for series connection = 11.1 /3.7 = 3 nos Commonly cells in series are abbreviated in terms of 'S', so this pack will be known as a “3S pack”.
To make the battery pack, you have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of Volt, mAh/ Ah, or Wh. You have to connect the cells in parallel to reach the desired capacity (mAh ) and connect such parallel group in series to achieve the nominal voltage (Volt ).
In this project I will show you how to combine common 18650 Li-Ion batteries in order to create a battery pack that features a higher voltage, a bigger capacity and most importantly useful safety measures. These can prevent an overcharge, overdischarge and even a short circuit of the batteries. Let's get started! Step 1: Watch the Video!
From the previous step, it is clear that our battery pack is made up of 3 parallel groups connected in series ( 3 x 3.7V = 11.1V ), and each parallel group has 5 cells ( 3400 mAh x 5 = 17000 mAh). Now we have to arrange the 15 cells properly for making the electrical connection among them and with the BMS board.
Commonly cells in parallel are abbreviated in terms of 'P', so this pack will be known as a “5P pack”.When 5 cells are connected in parallel, ultimately you made a single cell with higher capacity ( i.e 4.2V, 17000 mAh ) Voltage (Volt) : The desired nominal voltage of the battery pack is 11.1V. The nominal voltage of each cell = 3.7 V
